Yogi,
Still following along. I like your valve train, the adjuster bolt is genius. I really like the rocker arms.

Thanks everybody for the kind comments! It's very much appreciated!  :cheers:

I didn't get as much done during the summer month as I'd hoped, but I still got a few bits and pieces done that I can share.

The flywheel is a straight forward turning job. First side done:



Second side finished:



The finished flywheel:



As a contrast to the mostly aluminum engine, I decided to cold blue the flywheel. Hopefully this will also help a little with corrosion protection.
I used Brownells Oxpho Blue. I haven't done any cold blue before, and I'm happy how it turned out. It's not as dark as a commercial black oxide finish, and has more of a blue tint to it.



The flywheel installed on the crankshaft using a locking assembly.



While I was bluing the flywheel, I decided to give the rockers the same treatment:



The rockers installed:



I also made the tappets and tappet guides:







Valve springs and spring retainers installed:



Push rods installed:




Hopefully with the days getting shorter and the temperatures cooler, I'll be getting more quality time in the shop and progress on the engine.

Thanks everyone for following along, and stay tuned for more...

Nice update and progress Yogi.

Are you using a hot or cold process for the blueing? You may have said before but I can recall.
Beautiful work on all the new parts!

Yogi,
I am curious about the flywheel mounting set up. Is that some sort of taper lock setup? Could you define how that is arranged.

Thank you guys for the compliments! It is very much appreciated  :cheers:

Dave, the blueing is a cold process. I used Brownells oxpho blue.

Art, it is a tapered bushing, like you said. A few thoughts of why I choose to go this route: All that's required, is a reasonably accurate shaft and bore. It will also guarantee a wobble free flywheel. The engine is quite "industrial" looking, so I felt I could get away with it...  8)

That's one nice engine.  Nice design, very nicely machined and finished.  I like the industrial look of it.

Thank you gentlemen for the kind comments!  :cheers:

For the carburetion, I'm planing on using a RC engine carburetor. To mount it to the engine, I need to build a flange.

Holding a long piece of aluminum in the vise, the first side is milled:



The stock is turned over, and the second side is finished:



The "holding stock" is cut off on the cold saw:



The saw cut is cleaned up, and the holes drilled:





The finished flange:




Stay tuned...
Yogi
